DESCRIPTION

FEATURES

The SC1540 and SC1540A are high performance low

dropout positive voltage regulators designed for use in

applications where power management is critical, such

as battery powered systems. Additionally, the

SC1540(A) provides excellent regulation over varia-

tions in line, load and temperature. Outstanding fea-

tures include low dropout performance at rated current,

fast transient response, internal current limiting and

thermal shutdown protection of the output device. A

very low quiescent current of 10µA in shutdown mode

reduces power dissipation. With three voltage options

available, the SC1540(A) comes in the popular SO-8

surface mount package.

•= Low dropout performance, 1.3V max

•= Full current rating over line and temperature

•= Fast transient response

•= +2% total output regulation over line, load and

temperature

•= 10µA max. quiescent current in shutdown

•= Three fixed output voltages

•= Line regulation 0.2% max.

•= Load regulation 0.4% max.

•= SO-8 package
